Abstract (en)

[origin: WO2008033438A2] Symmetrical and asymmetrical ad-hoc, wireless networks and a method for saving power in the same may include causing a first station to determine whether a second station has a master capability to buffer data traffic for the first station. A first station requests the second station to buffer the data traffic intended for the first station for a first predetermined period. The first station enters a first power save mode, and the second station buffers the data traffic for the first station for the first predetermined period. The first station exits the first power save mode after the first predetermined period and the second station sends the buffered data traffic to the first station. Both the first and second stations may have master capabilities, or only one of the first and second stations may have a master capability.
